LM4120IM5-3.3

Texas Instruments · Voltage Reference · SOT-23-5

LM4120IM5-3.3 from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 REF unconnected The REF pin must remain unconnected in all cases, and it is sensitive to noise and capacitive loading, so it should be isolated on the PCB as much as possible.
2 GND power_in Negative supply or ground connection.
3 Enable input Pull to VIN for normal operation; forcing this pin to ground turns off the output, and floating it is not recommended.
4 VIN power_in Positive supply; the device operates with input voltages from 2 V to 12 V.
5 VOUT output Reference output, sourcing or sinking up to ±5 mA of load current.
